Check this box to enable such port redirection setting.
Two options (Single and Range) are provided here for you to
choose. To set a range for the specific service, select Range.
In Range mode, if the public port (start port and end port)
and the starting IP of private IP had been entered, the
system will calculate and display the ending IP of private IP
automatically.
Enter the description of the specific network service.
Select the transport layer protocol (TCP or UDP).
Select the WAN interface used for port redirection. There
are eight WAN IP alias that can be selected and used for port
redirection. The default setting is All which means all the
incoming data from any port will be redirected to specified
range of IP address and port.
Specify which port can be redirected to the specified Private
IP and Port of the internal host. If you choose Range as the
port redirection mode, you will see two boxes on this field.
Type the required number on the first box (as the starting
port) and the second box (as the ending port).
Use the drop down list to specify an IP object. Or click IP
Object link to create a new one for applying.

one will be assigned automatically later.
Specify the private port number of the service offered by the
internal host.
